To all whom it may concern:

Be it known that I, LEE GADDIE, a citizen of theUnited States, residing at Wellington, in the county of Sumner and State of Kansas, have invented a new and useful Yieldable Gearing; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled'in the art to which it appertains to make and use the same.

This invention relates to a new and useful power transmitting wheel or pulley, adapted mainly for use between cream separators and the likeand gasolene engines or similar power generators.

The invention in its broadest scope aims as its primary object, to providea resilient connection between the wheel or pulley or gear and the shaft, so as to absorb the mechanical shocks and vibrations, incident to the working of the gasolene engine or other machinery, in connection with the pulley or wheel.- a

In the drawings there are disclosed certain features of construction, but in. practical fields these features may necessitate alterations, to which the applicant is entitled, provided the alterations are comprehended within'the scope of What is claimed.

The invention comprises further features and combinations of parts, as hereinafter set forth, shown in the drawings, and claimed.

In the drawings :Figure 1 is a view in elevation, showing the application of the pulley between the gasolene engine and I cream separator. Fig. 2 is an enlarged elevation of the wheel or pulley detached from the engine and cream separator. Fig. 3 is a transverse sectional view on line 33 of Fig. 2. Fig. 4 is a detail view of a cross head block carried'by the pulley or wheel. Fig. 5'is a view in elevation of a modified form 'of pulley or wheel. Fig. 6 is a sec tional view on line 66 of Fig. 5.

Referring more especially to the draw ings 1 designates the engine (which is shown in dotted lines) while 2 denotes the cream separator. Loosely journaled upon the shaft 3 of the cream separator is a gear wheel 4, but in Figs. 2, 3 and 4 the wheel 4 is shown as a pulley wheel. Made fast to the shaft 3, by means of the set screws 5 are the collars6, one being arranged upon each side of the, wheel4.

In Figs. 1 to 4 inclusive, the wheel 4 is provided with a slot 7, in which a cross head block 8 is slidably arranged. Also arranged in the slot between the ends of the cross head block, and the ends of the slot are springs 9, which hold the cross head block yieldably or resiliently centered in the slot. The tensionof the springs 9 may be regulated by the devices 10.

Passing through the cross head block is a one piece spring member 11. On each side of the wheel 4 this spring member 11 is turned into helical springs 12, the ends of which are anchored to the collars 6, as shown at 13.

In Figs. 5 and 6, the spring member passes through the wheel 4, and the'slot 7 is dispensed with.

From the foregoing it will be apparent,

that any sudden or irregular movement of the driving shaft of the gasolene engine (which as a rule vibrates considerably incident to the explosion of the charges) will be absorbed or compensated by the buffer spring 9, thereby transmitting power to the cream separator in a smooth uninterrupted or regular manner.

The invention having been set forth, what and connected to the collars, the springs having resilient connections withthe wheel.

3. In combination,a shaft, a wheel loosely journaled thereon, collars fixed to the shaft, one upon each side of the wheel, and helical springs arranged on each side of the wheel and connected to the collars, the wheel having a semi-annularly arranged slot adjacent name to this specification in the presence of the periphery, a member slidably arranged two subscribing witnesses. in the slot, resilient means located between the member and the ends of the slot, the 1 LEE 5 helical springs having connections with the Witnesses:
